Okay, so the last series was bobbins, but 24 has bounced back before and we're hoping the forthcoming Season 7 will see the Jack Bauer Power Hour back on form. At its best, there is just nothing like it - insane levels of adrenaline, finely calibrated political intrigue and twists that hit you in the face like a two-fisted punch from Tony Almeida. 24 is some of the most cinematic TV you'll ever see, with no expense spared to depict CTU's intense battles against cunning terrorists and occasionally the odd rogue President. Even when 24's rubbish, it's still loveable - we still have a soft spot for the cougar who menaced Kim Bauer in possibly the show's worst ever plot twist, back in Season 2.

6:00 AM - 7:00 AM (Season 3, Episode 18). The gut-churning episode where terrorists demand that Jack shoot his supervisor Ryan Chappelle in the head or they'll kill thousands. As Jack puts a bullet into Ryan's head and weeps, the clock at the end of the episode remains silent, capping off the most emotional and darkest hour in 24's history.

James Morrison, who plays Bill Buchanan, runs a yoga class in Los Angeles, which Empire's Nick de Semlyen has attended and does not recommend for beginners.
